Besides the Serpentine Belt and the Timing Belt, what other belts are on my non turbo 2003 PT Cruiser? I keep getting a squealing noise from my car. My mechanic keeps changing a belt, but just after 75 to 200 miles it starts squalling again. I think it is the Serpentine belt that is making the noise because if I spray it (just behind the passenger front tire), it will temporally stop squalling but only for a few minutes. My mechanic tells me to never use belt dressing after he had to clean it up the last time. I don't use belt dressing anymore. My mechanic can't find the cause of the sequel but he also cant tell me how many belts I have on my car. I love my mechanic and I love my car, but I am losing faith in both of them. I'm hoping you can help us all. What can we do to stop the squealing in my car?
